However, not everyone was as thrilled of the star - who shot to fame in 2012 series of the singing competition - as she was forced to fight back against a troll criticising her looks.

The person wrote on a photo of her in a suit: "You dress like a 50yrs old lawyer whos due in court.. you're only young but your new dress sence is terrible, you've done so well getting yourself healthy but why change what you wear, you've changed to much of yourself.

"Surely your old taste in clothing was more real?! [sic.]"

Lucy hit back, saying: "You think I wear bespoke suits every day? Even if I did, why the fuck would it have anything to do with you? I’ve been working with King and Allen since I was a porker, love.

"I have no idea why losing weight has encouraged people to make open comments about me.

Stop it."

She also re-posted it on Instagram and wrote to her followers: "Believe it or not, losing a few stone and wearing a bespoke suit (which I’ve been into for nearly 4 years) doesn’t make me a whole other person. (I wear tracksuits 99% of the time anyway 😂).

"Everybody evolves, some people devolve, but the fact is we are always changing. And that is fine, that is natural.

"Right now I am the best version of myself I’ve ever been and I’m working incredibly hard to keep that going."
